Answer: The right answer is the B) She feels suffocated by her marriage to him.
Explanation: Just to elaborate a little on the answer, it can be added that although she feels grief after having been told (although mistakenly so, as the reader later discovers) that his loving husband Brently has died in a railroad accident, later on, alone in her room, Louise soon starts to realize that she is now an independent and free woman, and she feels joy. There is no specific reference to the way in which her husband might have oppressed her, so it is inferred that, for her, marriage in general, as an institution, is oppressive.
